4A Lunderquist Guide Wire

SKU: 4A-RA-0006

The Lunderquist Guide Wire (Extra Stiff / Ultra Stiff) is a heavy-duty interventional wire designed to provide maximum structural support during complex sheath exchanges and heavy device delivery. Engineered with a high-tensile stainless steel core, it resists bending and buckling under significant axial loads. Featuring a short flexible distal tip to protect internal tissue, the Lunderquist Wire is an essential component for delivering large-bore access sheaths in PCNL, aortic stent-graft placements, and severe ureteral dilations.

Key Benefits

  • Ultra-High Column Strength: Delivers maximum rigidity to support heavy dilators, large sheaths, and endovascular grafts.
  • Atraumatic Soft Distal Tip: Short flexible tip segment prevents tissue trauma while the rigid shaft stabilizes the track.
  • PTFE Coated Shaft: Smooth fluoropolymer coating reduces friction inside catheter lumens during exchange.
  • Kink-Resistant Stainless Steel Core: Engineered to maintain axial alignment under heavy torque and push forces.
  • Precise Fluoroscopic Control: Gold-plated or tungsten-marked distal tip provides visual depth confirmation under X-ray.

4A PTFE Guide Wire (SS)

The PTFE Guide Wire (Stainless Steel) is a foundational workhorse guide wire used across general surgical, urological, and radiological procedures for standard catheterization and device exchange. Constructed from a precision-wound stainless steel coil surrounding a central core wire, it is coated with smooth Polytetrafluoroethylene (PTFE). This fluoropolymer coating lowers surface friction, minimizes tissue drag, and resists clot adhesion, providing reliable daily performance in routine diagnostic and therapeutic access.

4A Abscess Drainage Catheter with Trocar

The Abscess Drainage Catheter with Trocar is a direct-puncture drainage device designed for single-step percutaneous evacuation of fluid collections. By integrating a sharp inner trocar stylet directly inside the radiopaque catheter body, it allows clinicians to penetrate skin, fascia, and the target cavity in a single motion, bypassing the multi-step wire placement process. Ideal for easily accessible, superficial, or large fluid collections, it provides immediate drainage access while minimizing procedure time.
